Hair coloring method

ABSTRACT

A method for coloring hair on a human head using a blow dryer is provided. According to the method, the hair is separated into sections of different shape (e.g., rhombic, square, triangular, horseshoe-shaped, etc.). Then, subsections of hair are isolated in each section. Each subsection of hair is grabbed and pulled (in a direction of a cut line of the hair) with one hand of a hairdresser, and different (e.g., short, medium-length, and long) layers of hair are blown out of the subsection of hair by an air flow from the blow dryer held in another hand of the hairdresser. After that, at least one of the blown-out layers of hair is fixed (e.g., with a clamp) and colored. The hair thus colored is then rinsed and treated according to a post-coloring recipe.

TECHNICAL FIELD

The present disclosure relates to the field of hairdressing, and morespecifically to a hair coloring method. The coloring method disclosedherein can be applied in beauty salons using well-known color formulas,to obtain a desired result on hair, with a smooth transition from darkto light hair tone and a high variability of coloring.

BACKGROUND

Currently, highlighting and complex hair coloring are widely known andcommonly used methods for coloring human hair, which result in acombination of natural hair and dyed hair.

The highlighting method involves determining the highest point of ahuman head in its natural position, isolating a main section of hairfrom the human hair growing from the highest point of the human head,separating the main section of hair into smaller elementary subsectionsof hair, and applying a hair dye (for example, to every secondelementary subsection of hair). Next, sections of hair growing below thehair of the main section of hair are isolated, and for each of them theabove-described steps are repeated. After holding a temporary pausesufficient for the hair to be dyed, the dye is washed off the humanhead. It should be noted that different hairdressers isolate certainsections of hair from the human hair in any sequence, but thehighlighting itself is characterized by the obligatory presence of thestep of separating sections of hair into smaller elementary subsectionsof hair and the step of selectively coloring the elementary subsectionsof hair. As a rule, the same hair dye is used for coloring theelementary subsections of hair.

As a result of the above-described highlighting method, the combinationof natural hair and dyed hair is formed. In addition, the natural hair“masks” the regrown hair roots, for which reason a person who hascolored his/her hair according to the highlighting method may notretouch his/her hair as often as a person who has colored his/her hairin the usual way.

The complex hair coloring method involves determining the highest pointof a human head in its natural position, isolating a main section ofhair from the human hair growing from the highest point of the humanhead, and applying a hair dye to this section of hair. Next, a sectionof hair growing below the hair of the main section of hair is isolated,and a different (in color) hair dye is applied to this section of hair.After that, the steps of isolating and coloring sections of hair arerepeated, while usually changing the color of an applied hair dye. Afterholding a temporary pause sufficient for the hair to be dyed, the hairdye is washed off the human head. It should be noted that differenthairdressers isolate certain sections of hair from the human hair in anysequence, but this coloring method is characterized by using hair dyesof different colors for neighboring sections of hair.

Interesting hairstyles are also obtained from the hair colored by usingthe complex hair coloring method, since it allows obtaining thecombination of sections of hair colored in different colors. Inaddition, the hair colored in this way also “masks” the regrown hairroots quite well, for which reason a person how has colored his/her hairaccording to the complex hair coloring method may not retouch his/herhair as often as a person who has colored his/her hair in the usual way.

The above-described hair coloring methods are characterized in thatimmediately after coloring, the dyed hair has the same color along itslength. After some time, the hair grows and the root section of the hairis of a different color than the colored section of the hair, whichmakes a hairstyle, sooner or later, less attractive. Even though thehighlighting and complex hair coloring methods allow one to “mask” thisflaw, all the same, after a while, hair retouching is inevitable. Inthis case, both the regrown sections of the hair and the sections thathave been previously colored and do not require additional coloring aresubjected to such retouching, which unnecessarily injures the hair.

RU2308861 discloses a method for coloring the hair of a human head, atthe beginning of which the highest point of the human head in itsnatural position is determined. A main section of hair is isolated fromthe hair growing from the highest point of the head. A first hair dye isapplied to the root section of the main section of hair. Sections ofhair growing below the hair of the main section of hair are sequentiallyisolated, and the first hair dye is applied to the root sections of theisolated sections of hair. A second hair dye, the color of which islighter than the color of the first hair dye, is applied to thosesections of the isolated sections of hair which are free from the firsthair dye. After holding a temporary pause sufficient for the hair to bedyed, the hair dyes are washed off the hair of the human head. As aresult, the human hair along their length is dyed in different (in tone)colors, while eliminating the need to retouch the root sections of thehair for a long time.

However, the method disclosed in RU2308861 does not allow one to obtainsmooth and soft color transitions on the hair. Furthermore, it does notallow one to correct the root zone without affecting the previouslylightened or previously dyed hair, which is important for shades of“blond” and all complexly colored options.

Currently, the peak of popularity in the field of hair coloring belongsto naturalness, giving the hair the most natural shade, while the hairshould also look healthy and vibrant.

The classical highlighting method has undergone major changes, resultingin the following coloring techniques: shatush, ombre and balayage. Eachof them gives the hair a natural effect of fading in the sun, and in allhair, there is a contrast between the roots and tips.

Shatush provides a smooth transition from dark to lighter shades and ischaracterized by its principle of applying a hair dye. This process isperformed in according with the “free-hand technique”, i.e., withoutusing additional tools and means, and even without foil.

The hair dye or lightener is applied with a conventional coloring brush.Before that, the hair is separated into thin sections of hair and combedfrom the roots. This will allow one to create an “air cushion” that willprevent excessive staining of the section of hair. Thus, the hair dyewill affect only individual upper hairs, which will provide animperceptible color transition.

The tips of the hair are more abundantly stained, and closer to theroots, the hair dye is stretched in thin stripes. Sometimes a singlesection of hair is colored in a V-shape.

At the same time, negligence in the performance of actions does notadversely affect the result. The lighter and more chaotic the shade isapplied, the more natural the hairstyle will look. Shatush is mostsuitable for brunettes and brown-haired women. Shatush requires morefrequent adjustments, once a month. Everything depends on the selectedshade and the speed of hair growth. Shatush is a coloring method inwhich a colorist uses two or three similar (in tone) shades as close aspossible to the natural color of the hair. Due to the soft stretching ofthe dye along the sections of hair, the effect of sun-faded hair withslight highlights is achieved. However, the bouffant does not allow oneto get as close as possible to the roots and does not allow one to doparallel manipulations with the hair that remained outside thelightening, i.e., which are directly in the bouffant.

Ombre is translated as “shadow” and, unlike shatush, has a clearerborder of color transition. This is a multi-stage hair coloringtechnique. It allows one to obtain natural overflows of several shadesof color—for example, from light blond to dark chestnut. To make thecolor transition noticeable, ombre is applied to dark sections of hair.The transition is made from a dark root zone to light tips. In thiscase, the border in the middle between the two shades is blurred. Thetransition to a light tone can begin from the middle of the hair length.

When coloring, a hair dye is applied to a selected area and covered withfoil. After the expiry of the time required for the hair to be dyed, thedye is washed off. The dye is re-applied to the previously treated area,shifting the top line by a couple of centimeters. It is again coveredwith foil, and after a while the dye is washed off. Ombre is suitablefor haircuts with short hair. It looks more impressive on dark hair.

Balayage means “sweep” in French, since the work of a hairdresser with abrush when applying a coloring composition to the hair resembles widesweeps of a broom.

When using balayage, the ends of the hair and sections of hair arehighlighted with color, starting from the middle.

A hair dye is applied in a V-shaped or W-shaped manner. First, the sidesof a selected section of hair are colored, and then its ends. Two orthree shades are used, “flowing” into each other. Color transitions canbe sharp or smooth, without clear boundaries.

Unlike shatush, the coloring composition is applied to the entire area,i.e., the lower part is highlighted more clearly. In this balayage issimilar to ombre. However, the shades used in the former case are closerto a natural hair color. In addition, balayage involves vertical ratherthan horizontal coloring, which results in more blurred transitions ofshades. Thus, one can say that balayage is something between shatush andombre.

All the above-described coloring methods, with the exception of shatush,involve working with the sections of hair in a plane, not allowing oneto separate the dyed hair into dark and light and color only those partsof the hair in the sections which need coloring or color correction. Inaddition, these methods do not allow one to obtain a predictable desiredresult on the hair, to obtain a smooth transition from a dark tone to alight tone of the hair and a high variability in coloring.

Shatush is meant to work with volume, and coloring is done randomly, forwhich reason shatush is not intended to obtain a desired result on thehair.

The common problem of light (blond) hair, which consists in dullness andloss of color, is well known. This is due to the high susceptibility oflight sections of hair to the environment and the cosmetics used. Blondehair is kind of empty. They are light due to the fact that they lackcolor pigments. That is why the hair of blondes tend to often changeshade, giving off yellowness or grayness. Also, every blonde, especiallynatural, has observed such a phenomenon as a difference in shade at theroots, along the entire length and at the tips. This phenomenon iscaused by the fact that bleached light hair tends to absorb the elementsof the environment. Smog, tobacco smoke, dirt, precipitation settle onthe hair and change their shade, giving yellowness or grayness. Hairchanges color from the fact that elements of a polluted environment fallunder their scales. In addition, regrown and previously colored blondhair needs color correction both in the root zone and along the entirelength of the sections of hair.

In reality, a section of long light hair has an uneven color along itslength: uncolored hair in the root zone has a natural color; furtheralong the entire length it acquires yellowness; at the ends—gray; inpreviously dyed blond hair in the root zone, regrown hair has a naturalcolor, darker than along the entire length; further along the entirelength it has a previously colored color or acquired yellowness.

The need to maintain a beautiful, even blonde color forces blondes toresort to frequent dyeing or color correction of the hair, which leadsto unnecessary damage to the hair, dryness and brittle ends of the hair.As a result, there are few blondes with healthy hair lengths in theworld.

All existing methods for coloring blond hair do not allow one toseparate the dyed hair into dark and light and color only those parts ofthe hair in the sections of hair which require dyeing or colorcorrection. In the known methods, coloring or dyeing is carried outalong the entire length of a section of hair, a hair dye is applied bothto recently colored areas and to newly grown areas or areas requiringcolor correction, which causes damage to the hair. In addition, theknown methods do not allow one to obtain a predictable desired result onthe hair, to obtain a smooth transition from a dark tone to a light toneof the hair and a high variability in coloring.

SUMMARY

This summary is provided to introduce a selection of concepts in asimplified form that are further described below in the detaileddescription. This summary is not intended to identify key features ofthe present disclosure, nor is it intended to be used to limit the scopeof the present disclosure.

It is an objective of the present disclosure to provide a technicalsolution that enables efficient hair coloring, while providing themaximum preservation of the quality of hair with any kind of lighteningand with any color correction of the root zone.

The objective above is achieved by the features of the independent claimin the appended claims. Further embodiments and examples are apparentfrom the dependent claims, the detailed description, and theaccompanying drawings.

According to the present disclosure, a hair coloring method is provided.All steps of the method are intended to be performed by a hairdresser.The method starts with the step of separating hair on a head of a personinto sections (e.g., rhombic, square, triangular, horseshoe-shaped,etc.) by parting the hair based on anatomical points of the head. Then,the method proceeds to the step of isolating, in each of the sections ofthe hair, subsections of hair based on a direction of hair growth in thesection. Each of the subsections of hair comprises a layer of long hairand a layer of short hair. Next, the method goes on to the followingsteps performed on each of the subsections of hair:

-   -   grabbing the subsection of hair with one hand close to an end of        the layer of long hair;    -   holding a blow dryer in another hand and directing an air flow        from the blow dryer through the subsection of hair, while        pulling away the subsection of hair in a direction of a cut line        of the hair, thereby gradually blowing the layer of short hair        out of the subsection of hair;    -   fixing each of the layer of long hair and the layer of short        hair with a clamp;    -   sequentially removing the clamps and coloring the layer of long        hair and/or the layer of short hair by using a color formula;    -   wrapping the colored layer of long hair and/or the colored layer        of short hair in a foil; and    -   upon expiry of a time period prescribed for the color formula,        removing the foil from the colored layer of long hair and/or the        colored layer of short hair;

When all the isolated subsections of hair are treated in this way, themethod proceeds to the step of rinsing the color formula off the hair.After that, the method goes on to the step of treating the hairaccording to a post-coloring recipe.

By using the method according to the present disclosure, it is possibleto color only required parts of the hair in the subsections of hair(i.e., those parts of the hair which require dyeing or colorcorrection). Thus, the method according to the present disclosure allowsone to achieve a desired result on the hair (e.g., to obtain a smoothtransition from a dark tone to a light tone of the hair).

In one embodiment, the step of coloring by using the color formulacomprises applying at least two different colors to the layer of longhair and/or the layer of short hair. By doing so, it is possible toprovide a high variability in hair coloring.

In one embodiment, the step of coloring by using the color formulacomprises applying the color formula to the subsections of hair in aform of a horizontal or zigzag pattern. By doing so, it is possible toensure a smooth transition from one color to another between thesubsections of hair.

In one embodiment, the method further comprises the step of tinting eachof the subsections of hair, after the step of rinsing the color formulaoff the hair but before the step of treating the hair according to thepost-coloring recipe. Said tinting may allow one to neutralize unwantedshades.

In one embodiment, the step of coloring by using the color formula isperformed in accordance with a graphic coloring scheme which shows thelayer of long hair in the subsection of hair as a first triangle and thelayer of short hair in the subsection of hair as a second triangle. Thefirst triangle has a base representing a root hairline and an apexrepresenting an end of the subsection of hair. The second triangle issmaller than the first triangle and is shown in the graphic coloringscheme as extending beyond the first triangle. In this embodiment, thegraphic coloring scheme further shows a border of a root zone,boundaries of coloring areas, and the color formula to be applied ineach of the first triangle and the second triangle. By using the graphiccoloring scheme, the whole hair coloring method may be performed quicklyand conveniently for the hairdresser (i.e., the hairdresser does notneed to keep in mind all the information about colors and/or tones to beused for a particular person; instead, the hairdresser can simply findit in the graphic coloring scheme).

Other features and advantages of the present disclosure will be apparentupon reading the following detailed description and reviewing theaccompanying drawings.

DETAILED DESCRIPTION

Various embodiments of the present disclosure are further described inmore detail with reference to the accompanying drawings. However, thepresent disclosure may be embodied in many other forms and should not beconstrued as limited to any certain structure or function discussed inthe following description. In contrast, these embodiments are providedto make the description of the present disclosure detailed and complete.

According to the detailed description, it will be apparent to the onesskilled in the art that the scope of the present disclosure encompassesany embodiment thereof, which is disclosed herein, irrespective ofwhether this embodiment is implemented independently or in concert withany other embodiment of the present disclosure. For example, the methoddisclosed herein may be implemented in practice by using any numbers ofthe embodiments provided herein. Furthermore, it should be understoodthat any embodiment of the present disclosure may be implemented usingone or more of the features presented in the appended claims.

The word “exemplary” is used herein in the meaning of “used as anillustration”. Unless otherwise stated, any embodiment described hereinas “exemplary” should not be construed as preferable or having anadvantage over other embodiments.

In the embodiments disclosed herein, the terms “colored (layer of) hair”and “dyed (layer of) hair” are used interchangeably, so that each ofthem refers to (layer of) hair having a color formula (or, in otherwords, hair color or dye) applied thereto.

The embodiments disclosed herein refer to a method for coloring hair ona human head using a blow dryer. The method is the result of experimentscarried out by the present inventor over two years. According to themethod, the hair is separated into sections of different shape (e.g.,rhombic, square, triangular, horseshoe-shaped, etc.). Then, subsectionsof hair are isolated in each section. Each subsection of hair is grabbedand pulled (in a direction of a cut line of the hair) with one hand of ahairdresser, and different (e.g., short, medium-length, and long) layersof hair are blown out of the subsection of hair by an air flow from theblow dryer held in another hand of the hairdresser. After that, at leastone of the blown-out layers of hair is fixed (e.g., with a clamp) andcolored. The hair thus colored is then rinsed and treated according to apost-coloring recipe.

Basic Concepts, Terms, and Definitions

Layer of Hair

Each hair has a trunk (shaft) protruding from the scalp and root. Thelower, expanded part of the hair root is called the bulb. Due to thebulbs, hair grows, as well as new hair is formed. The life cycle of thehair consists of three stages; its duration varies from 2 to 5 years.Each hair follicle is genetically programmed to produce approximately25-27 hair shafts. Each hair lives according to its “individualschedule,” and therefore different hairs are at the same time atdifferent stages of their life cycle: 85% of the hair is in the activegrowth phase (anagen), 1% of the hair is in the resting phase (catagen),and 14% of the hair is in the stage of prolapse (telogen). The length ofeach hair depends on what phase it is in. The smallest length ispeculiar to a newly starting hair, the so-called underhair. The greatestlength of hair is in the resting phase before hair loss or during hairloss.

FIGS. 1A and 1B show schematic top and side views, respectively, ofdifferent layers of hair in a subsection of hair. In other words, FIGS.1A and 1B show the subsection of hair with different hair growth phases.The subsection of hair itself is schematically shown as an elongatedtriangle. If the subsection of hair is exposed to an air flow from ablow dryer, it is separated from the shortest to the longest (see FIG.1B), i.e., a “fan” is created. These hair groups of different lengthsare herein referred to as layers of hair. The length and thickness oflayers of hair vary between people. The number of layers of hair in thesubsection of hair depends on the activity of the growth phases. At theend, the subsection of hair contains the longest hair, but contain onlya small amount of long hair, while the roots have the shortest hair, anda large number of them. A rapid change in the growth phases (quicklyregrown hair) indicates a high activity of the layers of hair, i.e.,many layers of hair.

When coloring according to the proposed method, each subsection of hairis pulled away, with one hand of a hairdresser, in the direction of ahair cut line, directing a cold air flow from the blow dryer through thesubsection of hair. By doing so, one part of the hair is “blown out”(i.e., layers of shorter hair), and another part of the hair (i.e.,layers of longer hair) remains in the hand of the hairdresser.

Grabbing Level

As used in the embodiments disclosed herein, a grabbing level is thedistance from the root zone, at which the hairdresser holds a givensubsection of hair with his/her fingers when blowing the subsection ofhair with the blow dryer. The grabbing level determines the ratio oflight and dark colors in the colored subsection of hair. When the layersof hair are highly active, the grabbing level is taken higher, i.e.,closer to the root zone, where the dark color of regrown and newly grownhair dominates.

Coloring Scheme

According to the embodiments disclosed herein, a coloring scheme is aplan for a coloring process, which the hairdresser draws after studyingthe condition of hair. The coloring scheme may include, but not limitedto, the boundaries of the application of color formulas (i.e., hairdyes), a post-coloring recipe, color formula numbers, and theirpercentage on each layer of hair. For convenience, the coloring schememay be presented graphically.

FIG. 2 shows a schematic top view of a subsection of hair with twodifferent layers of hair. More specifically, the subsection of haircomprises a layer of long hair and a layer of short hair. The layer oflong hair is schematically shown as a base (elongated) triangle 22,while the layer of short hair is schematically shown as a smallertriangle 21. The base triangle 22 may have a base corresponding to aroot hairline and an apex corresponding the end of the subsection ofhair. The smaller triangle 21 is applied to the base triangle 22.

FIG. 3 shows a graphic coloring scheme for the subsection of hair fromFIG. 2 . As shown in FIG. 3 , for visualization, the smaller triangle 21corresponding to the layer of short hair extends beyond the basetriangle 22, so that the hairdresser can indicate correspondingcoloring-related information thereon (e.g., shades, etc.). As should beapparent, the number of the triangles (i.e., layers of hair) shown inFIG. 3 is given for illustrative purposes only and should not beconstrued as any limitation of the present disclosure. In general, theremay be more than two triangles shown in the graphic coloring scheme,with each of them corresponding to a certain layer of hair (i.e., alayer constituted by hair of certain length) and being provided withcertain coloring-related information, such as the border of the rootzone, the border of the application of color formulas, color formulanumbers, shades, mixtures, and their percentage on each layer of hair,etc.

Hair Separation Scheme

As used in the embodiments disclosed herein, a hair separation scheme isa scheme according to which hair on a human head is separated intosections or zones, taking into account the anatomical features or pointsof the head. The hair separation scheme is applied at the beginning ofthe hair coloring method according to the present disclosure.

FIGS. 4A-4C show a classical scheme for separating hair on a human headinto sections. The classical separation is based on the anatomicalfeatures of the shape of the human skull, with some certain metriccharacteristics (dimensions, lines of curvature, transitions,depressions, bulges, etc.). The sections are artificial lines thatseparate and divide the scalp into zones to facilitate access andprovide the ability to work with each zone separately.

The area of the scalp is a certain section of the scalp that isallocated by the hairdresser in the coloring process. The followingclassical zones are known in hairdressing: frontal-parietal zone (FPZ),temporal-lateral zone (TLZ), upper occipital zone (UOZ), middleoccipital zone (MOZ) and lower occipital zone (LOZ).

The FPZ is limited in front by the edge of hair growth on the forehead,behind—by the upper part of the nape (along the central radial parting),and on the sides by the temporal-lateral zones. It is in the FPZ thatthe bulk of the hair volume is formed. The hair in the FPZ grows mainlyfrom the top of the head to the face. The main hair whorl is at the topof the head, along its border, and determines the streaming anddirection of hair growth. In the FPZ, there is a natural parting (theonly strip of skin against the background of hair), which can be in themiddle, left, right, diagonally, or completely absent. The FPZ iscrucial in solving the general appearance of a model. Therefore,according to the present disclosure, the central sections in the form of“rhombus”, “square”, “triangle”, “horseshoe” are provided in the FPZ.

The left and right TLZs are limited, at the place of attachment of theauricle, by a vertical section and are adjacent to the FPZ.

The UOZ above the left and right ears is bordered by the TLZ. In theUOZ, there are two upper occipital tubercles and a mid-occipitaltubercle.

The direction or run of hair growth in the UOZ is a multidirectionalswirl. A part of hair grows towards the face, the other—down, to theneck, left and right in the area of the auricles. When coloring, thiszone requires a thorough and flexible approach. It is in this zone thatthe flaws of the skull shape, which affect the solution of the tasks ofthe hairdresser, clearly manifest themselves.

The MOZ rests against the auricles on the left and on the right, borderson the UOZ at the top, and the bottom line of this zone repeats the baseof the skull, which is perfectly palpable in this zone. Here, the hairgrows in the middle down to the neck, right and left in the direction ofthe auricles.

The lower occipital protuberance is on the lower border in the zone. Theline of the sagittal section passes exactly through it. The lowerboundary of the MOZ sharply goes deep and reduces the volume of thezone. The line of curvature of the outgoing volume causes difficultiesfor work on it.

The LOZ is located outside the surface of the skull, namely on the neck.Here, the hair grows down to the auricles. In areas to the left andright of the sagittal section, swirls are often observed, which in turncompletely change the natural growth of hair, up to the formation ofswirls with the opposite direction of growth.

FIGS. 5A-5C show a layout of anatomical points of the human head. Morespecifically, FIGS. 5A-5C show the following anatomical points:

-   -   CP—central point—the first point at the intersection of the        hairline and the extension line of a central vertical parting        11;    -   HPC—the highest point of the crown—the highest point of the head        at the intersection of a central radial parting 10 and the        central vertical parting 11;    -   MPC—the middle point of the crown—the point between HPC and LPC;    -   LPC—the lower point of the crown—the point at the intersection        of the central vertical parting 11 and a horizontal parting 12;    -   UPT—the upper point of the temple—the point on a vertical line        from the center of the pupil or bulge of the eyebrow to the        intersection with the hairline;    -   MPT—the middle point of the temple—the point at the intersection        of the hairline and the line of the jugular connection;    -   LPT—the lower point of the temple—the point in the recess near        the auricle;    -   O—the occipitalis—the point on the lower border of the nape        bulge.

All the points listed above are, for the most part, quite pronounced andcan be determined by touch.

FIGS. 5A-5C also shows one more point—PP—the projection point.

As for the central radial parting 10, it is an arch from ear to earthrough the crown. It separates the parietal zone from the upperoccipital.

As for the central vertical parting 11, it divides the upper and loweroccipital zones into two halves.

As for the horizontal parting 12, it separates the upper occipital zonefrom the lower, passes from ear to ear through the occipital tuberclesand the lower point of the crown (LPC).

FIG. 6 schematically explains a hair coloring method in accordance withone exemplary embodiment. According to the method, a hairdresser studiesthe condition of hair to be colored, determines a required number oflayers of hair and draws up a coloring scheme to obtain a desired resulton the hair. As noted earlier, the coloring scheme may graphicallypresent a subsection of hair in the form of a base (elongated) triangle(see FIG. 3 ), the base of which is a root hairline, while the apex ofwhich is the end of the subsection of hair. A smaller triangle isapplied to the base triangle, corresponding to a layer of shorter hair.For convenience, the smaller triangle extends beyond the base triangle.On each triangle-layer, a coloring scheme is applied, which may include,but not limited to, the border of the root zone, the border of theapplication of color formulas, a recipe, color formula numbers in eachlayer of hair.

Those skilled in the art will recognize that the terms “color formula”(or “dye”) and “color formula number” (or “dye number”) may also referto shades, tones, mixtones, and their ratios. Further in the text, theterms “color formula” and “color formula number” will be used in thissense.

Depending on the type of a haircut and the length of the hair, a schemefor separating the hair into sections according to the anatomical pointsof the head is selected (see FIGS. 5A-5C).

In each section, subsections of hair are isolated, and each subsectionof hair is fixed with a clamp. Depending on the activity of the hairgrowth phases corresponding to layers of hair in the subsection of hair,a grabbing level for the subsection of hair is selected.

As shown in FIG. 6 , the hairdresser grabs the subsection of hair inaccordance with the grabbing level and pull away in the direction of thehaircut. The hairdresser holds a blow dryer in the other hand anddirects an air flow from the blow dryer through the subsection of hair,step by step blowing out the layers of hair that are above the grabbinglevel, resulting in blowing out the layers of hair above the grabbinglevel. The blown-out layers of hair are denoted in FIG. 6 as layers B,C, D, and E. The rest hair (i.e., those in layer A) remains in the handfor coloring. Each blown-out layer of hair is fixed. A coloring formulais applied to each layer of hair in accordance with the coloring schemeand wrapped in a foil. A time period sufficient for coloring the hair ismaintained. To ensure a smooth transition from one color to anotherbetween the subsections of hair, the color formula may be applied to thesubsections of hair in the form of a horizontal or a zigzag pattern.Then, the color formulas are rinsed off the hair, and the hair istreated according to a post-coloring procedure.

During the initial coloring (first visit to the hairdresser), theseparation of each subsection of hair into two layers of hair is usuallyenough. During the secondary coloring (second visit to the hairdresser),the separation of each subsection of hair into three layers of hair isrequired. The longest layer of hair and the middle layer of hair aredyed with a lighter color; the color formula is applied according to thecoloring scheme. Color correction is carried out, if necessary. Duringthe third coloring (third visit to the hairdresser), the hairdresserworks with the shortest layer of hair, making the root zone colored witha lighter color, without affecting all other hair.

In more detail, the color correction can be described as follows.

If a client arrives four or more months after the coloring, then thehairdresser can separate the same first subsections of hair by using theblow dryer as explained above, and lighten the root zone, because thelight part is clearly separated from the dark and overgrown zone in thefirst layers of hair, which were colored four or more months ago. If theclient wants to add more light color, then without affecting the longsubsections of hair that have grown in the root zone, the hairdressercan take the middle layer of hair and add light tones to make a smoothertransition from the root zone.

At the next visit, one of two layers of hair is worked on: either thevery first, longest, or middle. Work is carried out with all threelayers, and alternately, every two to three months, replacing them witheach other, only in the case when a large amount of blond is needed,almost total blond.

When light stretching is needed, the hairdresser works with long layersof hair. A middle layer of hair is treated extremely rarely when darkgradient coloring is needed. If more blond is needed, the middle layerof hair is added. If even more blond is needed, then a third layer ofhair is added. In addition, it is possible to alternate between thelayers of hair.

Thus, the hairdresser can get all the layers of hair in the subsectionof hair. Over time, the hair grows and changes back to its originalcolor, but the proposed method allows the hairdresser to separate thelayers of light hair from the layers of dark hair and color onlyrequired areas of the hair. The hairdresser can predict a year ahead andschedule the time when the correction of the colored hair can be donewithout injuring the hair, taking into account each individual case.

The proposed coloring method makes it possible to separate the coloredhair into dark and light, to highlight the hair to be colored, withoutaffecting the rest hair. If the hair does not need to be lightened, itwill not be damaged. The hairdresser works only with a layer of hairthat should be lightened. There is no other coloring method, where suchseparation of the subsection of hair into light and dark color isachieved. The method makes it possible to obtain a smooth transitionfrom a dark tone to a light tone over the entire volume of thesubsection of hair and a high variability of coloring, therebymaintaining maximum hair quality for any kind of lightening and for anycorrection of the root zone.

The following are non-limiting examples of the specific implementationof the proposed hair coloring method according to the first embodiment.

Example 1

A hairdresser studies the condition of hair to be colored, determinesthe number of layers of hair and draws up a coloring scheme to obtain adesired result on the hair. In this example, the matter concerns thehair of medium length (shoulder length), i.e., a bob haircut, and it isassumed that unsuccessful previous coloring led to the effect of burnthair. The hair is separated into subsections of hair in each section,and each subsection of hair is clamped. The activity of the hair growthphases allows the hairdresser to select two layers of hair with twograbbing levels. The hairdresser grabs the subsection of hair inaccordance with the first grabbing level, closer to the end of thesubsection of hair, and pull away in the direction of the haircut. Thelayer of shorter hair above the grabbing level are blown out with a blowdryer from the subsection of hair and fixed with a clamp. The rest ofthe hair in the subsection of hair is grabbed in accordance with thesecond grabbing level, closer to the roots of the hair, and fixed with aclamp. A coloring scheme is made, in which the layer of long hair isshown as the base (elongated) triangle 22 and the layer of shot hair isshown as the smaller triangle 21 extending beyond the base triangle 22.The coloring scheme also indicates color tones on each of the triangles21, 22 (i.e., for each of the two layers) (see FIG. 7 ). For the basetriangle 22 (i.e., the layer of long hair), color 6N (medium brown) isindicated in the region closest to the hair roots, color 8N (blonde) isindicated in the middle region, and color 10N (platinum blonde) isindicated in the remaining region. Correspondingly, for the smallertriangle 21 (i.e., the layer of short hair), color 6N (medium brown) isindicated in the region closest to the hair roots, and color 7N (lightbrown) is indicated at the ends corresponding to the middle region ofthe base triangle 22.

A foil is placed under each of the two layers of hair, and a colorformula is applied according to the coloring scheme.

A time period sufficient for the hair to be colored with the colorformula is maintained. Then, the color formulas are rinsed off the hair,and the hair is treated according to a post-coloring recipe.

As a result of such coloring, the desired effect is obtained—a beautifulblonde with a smooth transition of tones, i.e., the effect of thenatural color of burnt hair. This is one of the most difficult colorcorrections.

Example 2

The hairdresser studies the condition of the hair to be colored during asecond visit after the initial coloring. Secondary coloring is requireddue to the fact that a layer of regrown hair has appeared, which bringsa dark tone to the initially colored blond. The hairdresser determinesthe number of layers of hair. Hair growth activity allows thehairdresser to distinguish three layers of hair with two grabbinglevels.

The longest layer of hair is isolated and fixed with a clamp.Medium-length and short layers of hair are blown out from the remaininghair with an air flow from a blow dryer. Color correction is made on themiddle layer of hair by using tone 7N (light blond). The previouslycolored long layer of hair is lightened with tone 8N (blond). The shortlayer of hair is not affected and thus is not damaged.

Subsequently, the method is carried out as in Example 1.

As a result, the effect of burnt hair is “refreshed” and a smoothtransition of tones is obtained over the entire volume of the subsectionof hair, since in the subsection of hair, short layers of hair withdarker tones are added to longer layers of lightened hair, withoutcausing undue damage to short layers of hair.

Example 3

The hairdresser studies the condition of the hair to be colored during athird visit, i.e., after the secondary coloring. A layer of newlyregrown hair of the original color has appeared. Hair growth activityallows the hairdresser to separate the very first layer of hair.Consistently blowing out long layers of hair, the grabbing level isbrought closer to the root zone, taking out the very first layer ofnewly regrown hair. The hairdresser corrects this layer by using tone6N, without affecting the long layers of hair, and without unnecessarilyinjuring them.

Subsequently, the method is carried out as in Example 1.

Example 4

The hairdresser studies the condition of the hair to be colored. Theclient wants to brighten the hair. By using the highest grabbing level,the long layer of hair is isolated, blowing out all the short layers ofhair. The hairdresser then lays a foil under the long layer of hair andapply brightening composition 8N.

Subsequently, the method is carried out as in Example 1.

The above-given examples are not exhaustive; they are given only for thebest understanding of the proposed method.

To obtain a predicted desired result of hair coloring, it is necessaryto adapt the coloring process to a certain type of haircut to preventshort hair from falling out of the grip and, therefore, to have darkuncolored hair at the ends of the subsections of hair. In the proposedmethod, such a phenomenon is not possible.

The present inventor has adapted the hair coloring method to differenthair separation schemes, namely: “rhombus”, “square”, “triangle”, and“horseshoe”.

FIGS. 8A-8D show a scheme for separating hair on a human head intorhombic sections in accordance with a first exemplary embodiment. Thisscheme is suitable for the hair of the same length, for example, a bobhaircut.

The hairdresser studies the condition of the hair to be colored,determines the number of layers of hair and draws up a coloring schemeto obtain a desired result on the hair. The coloring scheme is visuallypresented in the same manner as described above.

The hairdresser selects the scheme of separating the hair into rhombicsections according to the anatomical points of the head.

The frontal-parietal zone (FPZ) of the head is crucial in deciding thegeneral appearance of the colored hair. However, the different directionof hair growth in this zone complicates the work of the hairdresser. Thehair in the FPZ grows mainly from the top of the head to the face. Atthe top of the head, along its border, there is the main swirl, whichdetermines the direction of hair growth. There is a natural parting inthe FPZ. To facilitate access to the layers of hair and the possibilityof obtaining a desired result on the colored hair, the FPZ is dividedinto diagonal section lines, highlighting a central rhombic section, asfollows:

-   -   the central radial parting 10 and the central vertical parting        11 are drawn through the highest point of the crown (HPC);    -   two parallel partings from the upper points of the temple (UPT)        to the projection points (PP) on the central radial parting 10        are drawn (see FIG. 8C);    -   a line segment equal to the distance from the HPC to the PP on        the central radial parting 10 is measured and laid from the PP        to an intersection with the central vertical parting 11 of the        projection, thereby obtaining two sides of a rhombus;    -   a segment equal to a segment from the HPC to the top of the two        resulting sides is laid on another side of the central radial        parting 10;    -   a resulting point is connected by the parting lines with the PP,        thereby obtaining the central section in the form of the rhombus        from the hair on the head of the person;    -   from the parting lines forming the rear sides of the central        rhombic section, the central vertical parting 11 and the central        radial parting 10, peripheral occipital sections 1 and 2 are        obtained relative to the central rhombic section according to        the anatomical points of the head;    -   from the lines of two parallel front partings and the central        radial parting 10, peripheral temporal sections 3 and 4 are        obtained relative to the central rhombic section according to        the anatomical points of the head;    -   from the parting lines forming the front sides of the central        rhombic section, the central vertical parting 11 and the two        parallel front partings, peripheral parietal sections 5 and 6        are obtained relative to the central rhombic section according        to the anatomical points of the head.

From the hair growing in the above sections, subsections of hair areisolated, which have directions shown in FIG. 8A-8D, namely:

-   -   in the occipital sections 1, 2 and the parietal sections 5, 6,        the direction of the subsections of hair is parallel to the        corresponding sides of the rhombic section;    -   in the temporal sections 3 and 4, the direction of the        subsections of hair is parallel to the hairline in the temporal        area;    -   in a rhombic section 7, the direction of the subsections of hair        is arbitrary, i.e., it can be vertical, horizontal, or diagonal.

Each subsection of hair is fixed with a clamp. Depending on the activityof the hair growth phases corresponding to the layers of hair, thegrabbing levels in the subsection of hair are selected.

The subsection of hair is held by one hand in accordance with thegrabbing level selected according to the coloring scheme. A blow dryeris held in the other hand, and an air flow from the blow dryer isdirected through the subsection of hair.

The subsection of hair is pulled away in the direction of the haircutaccording to the haircut, gradually blowing out short, medium-length,longer and longest hair from it, resulting in a required number ofblown-out layers of hair. By making the grabbing level higher, a nextlayer of hair is blown out. From each subsection of hair, a certainnumber of layers of hair is obtained, preferably from 1 to 3 layers.

A coloring formula is applied to the obtained layer of long hair inaccordance with the coloring scheme. The colored layer of hair iswrapped in foil. All the longest layers of hair in all subsections ofhair in each section are colored and wrapped. A next coloring formula isthen applied to a layer of short hair in accordance with the coloringscheme. Thus, all subsequent layers of hair in all subsections of hairin each section are colored and wrapped. The subsections of hair arecolored, either a few centimeters from the roots or right next to theroots, depending on the indication on the coloring scheme, in order toobtain a desired effect.

To ensure a smooth transition from one color to another between thesubsections of hair, the color formulas are applied to the subsectionsof hair in the form of a horizontal or zigzag pattern.

A time period is maintained, which is sufficient for the hair to becolored.

The color formulas are rinsed off of the hair.

The colored subsections of hair are tinted to neutralize unwantedshades.

The hair is treated according to a given post-coloring method.

Example 5

The hairdresser studies the condition of hair to be colored. This caserelates to the haircut of the same length, like a bob haircut. Thecorrection of previously colored hair is required. The activity of thehair growth phases allows the hairdresser to select two layers of hairwith two grabbing levels. The coloring chart is the same as shown inFIG. 3 .

The hairdresser selects the scheme for separating the hair into rhombicsections according to the anatomical points of the head (see FIGS.8A-8D). This hair separation into the rhombic sections is performed asdescribed above.

Each subsection of hair in each section is fixed with a clamp.

The subsection of hair is held by one hand in accordance with thegrabbing level selected according to the coloring scheme. Thehairdresser holds a blow dryer in the other hand and directs the airflow from the blow dryer through the subsection of hair.

The subsection of hair is pulled away in the direction of the cut lineof the hair. Short hair is blown out, leaving a layer of long hair inthe hairdresser's hand. The resulting layer is fixed.

A color formula is applied to the resulting layer of layer hair inaccordance with the 6N (medium blond) coloring scheme; in subsequentsections, in accordance with the grabbing level indicated in the scheme,lighter tones are applied: in the middle region—7N+8N (lightblond+blond), at the ends—9N+10N (bright blond+platinum blond). Thehairdresser wraps the colored layer of hair in foil. Thus, all firstlayers of hair in the subsections of hair in each section are colored. Anext color formula is then applied to a second layer of short hair inaccordance with the coloring scheme, for example, 6N at the roots and7N+8N (light blond+blond) in the subsequent region, and the second layerof hair is wrapped in foil. In this way, all second layers of hair inthe subsections of hair in each section are colored. The hairdressercolors the subsections of hair, retreating a few centimeters from theroots.

A time period is maintained, which is sufficient for the hair to becolored. To ensure a smooth transition from one color to another betweenthe subsections of hair, the color formulas is applied to thesubsections of hair in the form of a zigzag pattern.

The colored subsections of hair are tinted to neutralize unwantedshades. Then, the color formulas are rinsed off the hair, and the hairis treated according to a post-coloring method.

FIGS. 9A-9D show a scheme for separating hair on a human head intosquare sections in accordance with a second exemplary embodiment. Thisscheme is suitable for haircuts with bangs, and for hair trimmed with acascade (a bob haircut). In addition, the hair separation into thesquare sections solves the problem of obtaining a more uniform colorfrom roots to ends, e.g., a more even blond.

The hairdresser studies the condition of hair to be colored, determinesa required number of layers of hair and draws up a coloring scheme toobtain a desired result on the hair. The coloring scheme is visuallypresented as described above.

The hair is separated into the square sections according to theanatomical points of the head.

The square sections are formed according to the anatomical points of thehead by using partings.

To facilitate access to the layers of hair and the possibility ofobtaining the desired result on the colored hair, the FPZ is separatedby using diagonal, vertical and horizontal parting lines, whilehighlighting a central square section. To do this, the followingoperations are performed:

-   -   through the highest point of the crown (HPC), the central radial        parting 10 and the central vertical parting 11 are drawn;    -   through the lower points of the temple (LPT) and the point of        occipitalis (O), a horizontal parting 12 is drawn (see FIG. 9B);    -   two parallel parting lines are drawn, which extend from the        upper points of the temple (UPT) to the projection points (PP)        on the horizontal parting 12 and then to the hairline on the        lower occipital area;    -   from the midpoint of the crown (MPC), a horizontal line is drawn        to the intersection with the parallel parting lines, thereby        obtaining a central square section 14;    -   the resulting intersection points are connected by diagonal        lines with the midpoints of the temple (MPT) on the hairline of        the parietal zone, thereby obtaining first 15, second 16, third        17, fourth 18 sectors of the central square section (see FIG.        9A);    -   from the parting lines forming the vertical sides of the central        square section, the central vertical parting 11 and the        horizontal parting 12, peripheral temporal-occipital sections 8        and 9 are obtained relative to the central square section        according to the anatomical points of the head.

The lower occipital area, located under the horizontal parting 12, has asmall surface. In addition, swirls are often observed in this zone,which change the natural growth of hair, thereby causing difficulties inworking in it. The implementation of the hair coloring method accordingto the present disclosure involves diagonal sections that allow one tocreate stepless transitions of layers of colored hair. To do this, thehairdresser draws a diagonal line on the horizontal parting 12 to theprojection point (PP) on the hairline in the lower occipital area andobtains peripheral lower occipital sections 19 and 20 according to theanatomical points of the head. Hair in these sections are separated intosubsections of hair, taking into account the direction of hair growth inthe sections shown in FIGS. 9A-9E, namely:

-   -   in the lower occipital section 19, the direction of the        subsections of hair is parallel to the diagonal line separating        the occipital sections;    -   in the lower occipital section 20, the direction of the        subsections of hair is perpendicular to the diagonal line        separating the lower occipital sections;    -   in the temporal-occipital sections 8 and 9, the direction of the        subsections of hair coincides with the direction of natural hair        growth;    -   in the sectors 15, 16, 17, 18 of the central square section 14,        the direction of the subsections of hair is radial with respect        to the intersection point of the diagonals of the square.

Each subsection of hair is fixed. The subsection of hair is grabbed byone hand in accordance with the grabbing level selected according to thecoloring scheme. The other hand holds a blow dryer and directs the airflow from the blow dryer through the subsection of hair, which is pulledaway perpendicular to the surface of the head, thereby gradually blowingout short, medium-length, longer and longest hair. From each subsectionof hair, a certain number of layers is obtained, preferably 1 to 3layers. Each of those layers are fixed with a clamp.

The resulting layer of hair is colored according to the coloring schemeand wrapped in foil. All layers of hair in each subsection of hair ineach section are treated in this manner.

To ensure a smooth transition from one color to another between thesubsections of hair, color formulas are applied to them in the form of ahorizontal or zigzag pattern.

A time period is maintained, which is sufficient for the hair to becolored.

The color formulas are rinsed off the hair.

The subsections of colored hair are tinted to neutralize unwantedshades.

The hair is treated according to a post-coloring method.

Example 6

The hairdresser studies the condition of hair to be colored, determinesa required number of layers of hair and draws up a coloring scheme toobtain a desired result on the hair. This case concerns primary haircoloring with a cascading haircut. A client wants to get a smoothtransition from a darker color at the hair roots to a very light colorat the ends of the hair. The hairdresser selects the scheme forseparating the hair into the square sections according to the anatomicalpoints of the head (see FIGS. 9A-9D). The hair separation into thesquare sections is performed as described above.

Subsections of hair are isolated in each section, and each subsection ofhair is fixed with a clamp. The activity of the hair growth phasesallows the hairdresser to select two layers with two grabbing levels(see FIG. 3 ).

The hairdresser grabs the subsection of hair and holds it in thefingers, pulling away in the direction of the cut line of the hair.Layers of shorter hair above the grabbing level are blown out with ablow dryer. Each layer of hair is fixed with a clamp.

Then, the hair coloring process is performed as follows.

In each section, it is supposed to color the subsections of hair byusing a darker tone at the roots and making a transition to a light tone(blond) at the ends of the subsections of hair. The coloring schemeshown in FIG. 7 is used, which indicates the color tone numbers in eachlayer of hair. More specifically, in the base triangle 22 (denoting thelayer of long hair), color 6N (medium brown) is indicated in the regionclosest to the hair roots, color 8N (blonde) is indicated in the middleregion, and color 10N (platinum blonde) is indicated in the remaining(end) region. As for the smaller triangle 21 (denoting the layer ofshort hair), color 6N (medium brown) is indicated in the region closestto the hair roots, and color 7N (light brown) is indicated at the endscorresponding to the middle region of the base triangle 22.

The color formulas are applied to the obtained layers of hair inaccordance with the coloring scheme, whereafter the layers of hair arewrapped in foil. A time period is maintained, which is sufficient forthe hair to be colored. To ensure a smooth transition from one color toanother between the subsections of hair, the color formulas in the formof a zigzag pattern.

Then, the color formulas are rinsed off the hair, and the hair istreated according to a post-coloring method.

As a result of coloring, a uniform transition of tones from roots toends is obtained, i.e., an even blond.

FIGS. 10A-10E show a scheme for separating hair on a human head intotriangular sections in accordance with a third exemplary embodiment.This scheme makes it possible to obtain lighter subsections of hairaround the face and along the contour of hair growth, while leaving thetop darker. This allows the hairdresser to get the smoothest colorstretching. This scheme is suitable for both haircuts of one length, andfor hair cut in a cascade.

The hairdresser studies the condition of hair to be colored, determinesa required number of layers of hair and draws up a coloring scheme toobtain a desired result on the hair. The coloring scheme is visuallypresented as described above.

To facilitate access to the layers of hair and the possibility ofobtaining the desired result on the colored hair, the FPZ are divided byparting lines, obtaining a central triangular section, as well asperipheral sections relative to the central triangular section accordingto the anatomical points of the head. To do this, the followingoperations are performed:

-   -   through the highest point of the crown (HPC), the central radial        parting 10 and the central vertical parting 11 are drawn;    -   through the lower points of the temple (LPT) and the lower point        of the crown (LPC), the horizontal parting 12 is drawn (see FIG.        10B);    -   two parallel parting lines are drawn from the upper points of        the temple (UPT) to the projection points (PP) on the horizontal        parting 12 and then to the hairline on the lower occipital area;    -   from the center point (CP), lines are drawn to the intersection        with the PP on the radial parting 10 with the continuation to        the intersection with the horizontal parting 12, thereby        obtaining a central triangular section 26;    -   a crescent-shaped parting 23 is provided from the upper points        of the temple through the highest point of the crown (HPC);    -   lateral sectors 24, 25 and one central sector 26 of the        triangular section of the parietal zone are obtained (see FIG.        10C);    -   the extended lines of the sides of the triangle, the central        vertical parting 11 and the horizontal parting 12 form sections        27, 28 of the upper occipital zone;    -   the sections between the lines of the crescent-shaped parting        23, which border the lateral sectors 24, 25 of the triangle, the        horizontal parting 12 and the lines of the sides of the triangle        form peripheral sections 29, 30 of the temporal-occipital zone        according to the anatomical points of the head.

The lower occipital zone, located under the horizontal parting 12, has asmall surface. In addition, swirls are often observed in this zone,which change the natural growth of hair, thereby causing difficulties inworking in it. The implementation of the coloring method according tothe present disclosure involves diagonal sections that allow thehairdresser to create stepless transitions of the colored layers ofhair. To do this, the hairdresser draws a diagonal line 31 (see FIGS.10D and 10E) from one of the projection points (PP) on the horizontalparting 12 to the projection point (PP) on the hairline in the loweroccipital zone, thereby obtaining peripheral lower occipital sections 32and 33 according to the anatomical points of the head. Then, thesubsections of hair starting from the sections are isolated according totheir direction, namely:

-   -   in the lower occipital section 32, the direction of the        subsections of hair is parallel to the diagonal line separating        the occipital sections;    -   in the lower occipital section 33, the direction of the        subsections of hair is perpendicular to the diagonal line        separating the occipital sections;    -   in the temporal-occipital sections 29, 30, the direction of the        subsections of hair goes from the central point (CP) to the        horizontal parting 12;    -   in the sections 27, 28 of the upper occipital zone, the        direction of the subsections of hair is radial, from the center        point (CP) to the horizontal parting 12;    -   in the lateral sectors 24, 25 of the central triangular section,        the direction of the subsections of hair is radial, from the        central point (CP) to the crescent-shaped parting 23;    -   in the central triangular section 26, the direction of the        subsections of hair is parallel to the radial parting 10,        because the direction of the hair in this zone splits back and        forth.

The subsection of hair is held by one hand in accordance with thegrabbing level selected according to the coloring scheme. With the otherhand, the hairdresser holds the blow dryer and direct the air flow fromthe blow dryer through the subsection of hair, while pulled away it inthe direction of the cut line of the hair, thereby gradually blowing outshort, medium-length, long and longer hair from it. As a result, therequired number of blown-out layers of hair is obtained. By making thegrabbing level higher, the next layer of hair is blown out. From eachsubsection of hair, a certain number of layers of hair is obtained,preferably from 1 to 3 layers. Each obtained layer of hair is fixed andwrapped in foil. Then, the hairdresser proceeds to the hair coloringprocess.

Coloring formulas are applied to the obtained layer of hair inaccordance with the coloring scheme, the layer of hair is wrapped infoil. All layers of hair of each subsection of hair in each section aretreated in this manner.

To ensure a smooth transition from one color to another between thesubsections of hair, the color formulas are applied to the subsectionsof hair in the form of a horizontal zigzag pattern.

A time period is maintained, which is sufficient for the hair to becolored.

The color formulas are rinsed off the hair.

The colored subsections of hair are tinted to neutralize unwantedshades.

The hair is treated according to a post-coloring procedure.

Example 7

The hairdresser studies the condition of hair to be colored, determinesa required number of layers and draws up a coloring scheme to obtain adesired result on the hair. In this case, it is required to obtain morelight subsections of hair around the face and along the contour of hairgrowth, leaving the top darker. The coloring scheme is visuallypresented as described above.

This case concerns primary coloring for the hair cut in cascade. Thehairdresser selects the scheme for separating the hair into thetriangular sections according to the anatomical points of the head (seeFIGS. 10A-10D). The hair separation into the triangular sections isperformed as described above.

Subsections of hair are isolated in each section, and each subsection ofhair is fixed with a clamp. The activity of the hair growth phasesallows the hairdresser to select two layers of hair with two grabbinglevels.

The hairdresser grabs the subsection of hair and pull it away in thedirection of the cut line of the hair. Layers of shorter hair above thegrabbing level are blown out of the subsection of hair with a blowdryer.

Then, the hairdresser proceeds to the hair coloring process.

In sections near the face and along the contour of hair growth, a layerof long hair is colored with tone 10N (platinum blond), and a layer ofshort hair is colored with tone 9N (bright blond).

In the rest sections, the coloring process is performed according to thecoloring scheme used in Example 1 (see also FIG. 7 ). More specifically,in the base triangle 22 (denoting the layer of long hair), color 6N(medium brown) is indicated in the region closest to the hair roots,color 8N (blonde) is indicated in the middle region, and color 10N(platinum blonde) is indicated in the remaining (end) region. As for thesmaller triangle 21 (denoting the layer of short hair), color 6N (mediumbrown) is indicated in the region closest to the hair roots, and color7N (light brown) is indicated at the ends corresponding to the middleregion of the base triangle 22.

The coloring formulas are applied to the obtained layers of hair inaccordance with the coloring scheme, whereafter the layers of hair arewrapped in foil. A time period is maintained, which is sufficient forthe hair to be colored. To smooth out rough transitions of tones betweenthe colored subsections of hair, the color formulas may be applied tothe subsections of hair in the form of a horizontal or zigzag pattern.Then, the color formulas are rinsed off the hair, and the hair istreated according to a post-coloring procedure.

As a result of coloring, more light strands are obtained around the faceand along the contour of hair, and the top is left darker, with a smoothtransition of tones, since the layers of hair with darker tones areadded to the layers of lightened hair, thereby resulting in aninteresting new effect.

FIGS. 11A-11E show a scheme for separating hair on a human head intohorseshoe-shaped sections in accordance with a fourth exemplaryembodiment. This scheme makes it possible to set different patterns onthe hair. Changing the grabbing level in each subsection of hair, it ispossible to achieve noticeable visible highlights and more distinctlycolored subsections of hair. It is suitable both for hair of the samelength and for hair cut in a cascade style (a bob haircut).

The hairdresser studies the condition of hair to be colored, determinesa required number of layers of hair and draws up a coloring scheme toobtain a desired result on the hair.

To facilitate access to the layers of hair and the possibility ofobtaining the desired result on the colored hair, the FPZ is separatedby parting lines such that a central horseshoe-shaped section andperipheral sections relative to the central horseshoe-shaped section areformed according to the anatomical points of the head. To do this, thefollowing operations are performed:

-   -   through the highest point of the crown (HPC), the central radial        parting 10 and the central vertical parting 11 are drawn (see        FIG. 11B);    -   through the lower points of the temple (LPT) and the point of        occipitalis (0), the horizontal parting 12 is drawn;    -   two parallel parting lines are drawn from the upper points of        the temple (UPT) to the projection points (PP) on the horizontal        parting 12 and then to the hairline on the lower occipital area;    -   two lines parallel to the radial parting 10 are drawn at an        equal distance from the central point (CP) through the central        parting 11 to the intersection with the parallel parting lines        starting from the upper points of the temple (UPT), thereby        obtaining two rectangular sections—parietal 34 and        parietal-occipital 35;    -   a line is drawn from the center point (CP) to the intersection        point with the boundary line of the parietal section, thereby        obtaining a triangular section 36;    -   a crescent-shaped parting 37 is drawn from the intersection        points (PP) of the parallel parting lines with the border line        of the parieto-occipital section 35 through the midpoint of the        crown, thereby obtaining an upper occipital section 38 (see FIG.        11C);    -   the parietal section 34, the parietal-occipital section 35, and        the rounded upper-occipital section 38 form the central        horseshoe-shaped section.

The middle occipital zone, located under the crescent-shaped parting 37and above the horizontal parting 12, has a complex relief, repeating thebase of the skull, hair growth in the middle down to the neck, right andleft in the direction of the auricles, which causes difficulties to workin it. The implementation of the coloring method according to thepresent disclosure involves diagonal partings, which allows thehairdresser to create stepless transitions of the colored layers ofhair. A diagonal line 39 is drawn from one of the projection points (PP)on the crescent-shaped parting 37 to the projection point (PP) on thehorizontal parting 12; thus, two peripheral parietal-upper occipitalsections 40 and 41 are obtained according to the anatomical points ofthe head (see FIGS. 11D and 11E).

The lower occipital zone, located under the horizontal parting 12, has asmall surface. In addition, swirls are often observed in this zone,which change the natural growth of hair, thereby causing difficulties inworking in it. The implementation of the coloring method according tothe present disclosure involves diagonal partings, which allows thehairdresser to create stepless transitions of the colored layers ofhair. To do this, a diagonal line 42 is drawn from one of the projectionpoints (PP) on the horizontal parting 12 to the projection point (PP) onthe hairline on the lower occipital area, thereby obtaining twoperipheral lower occipital sections 43 and 44 according to theanatomical points of the head (see FIGS. 11D and 11E). The subsectionsof hair from these sections are isolated from each other according totheir direction, namely:

-   -   in the lower occipital section 43, the direction of the        subsections of hair is parallel to the diagonal line 42        separating the occipital sections;    -   in the lower occipital section 44, the direction of the        subsections of hair is almost perpendicular to the diagonal line        separating the occipital sections;    -   in the temporal-occipital sections 40 and 41, the direction of        the subsections of hair goes from the central point (CP) to the        horizontal parting 12;    -   in section 36 of the parietal zone, the direction of the        subsections of hair is parallel to the diagonal line separating        the parietal sections;    -   in the parietal section 34, the direction of the subsections of        hair is perpendicular to the diagonal line separating the        parietal sections;    -   in the parietal-occipital section 35, the direction of the        subsections of hair is perpendicular to the direction of the        subsections of hair in the adjacent parietal section 34;    -   in the upper occipital section 38, the direction of the        subsections of hair is perpendicular to the direction of the        subsections of hair in the parietal-occipital section 35.

The subsection of hair is held by the hairdresser in one hand inaccordance with the grabbing level selected according to the coloringscheme. With the other hand, the hairdresser holds a blow dryer anddirects the air flow from the blow dryer through the subsection of hair,while pulling it away in the direction of the cut line of the hair,thereby gradually blowing short, medium-length, long and longer hair outof the subsection of hair. As a result, the required number of blown-outlayers of hair is obtained. Making the grabbing level higher, it ispossible to blow the next layer of hair. From each subsection of hair, acertain number of layers of hair is obtained, preferably from 1 to 3layers.

Then, the hairdresser proceeds to the hair coloring process.

Coloring formulas are applied to the obtained layers of hair inaccordance with the coloring scheme, whereafter at least one of thelayers of hair is wrapped in foil. All layers of hair of each subsectionof hair in each section are treated in this manner.

To ensure a smooth transition from one color to another between thesubsections of hair, the color formulas are applied to them in the formof a zigzag pattern.

A time period is maintained, is sufficient for the hair to be colored.

The color formulas are rinsed off the hair.

Optionally, the colored subsections of hair are tinted to neutralizeunwanted shades.

The hair is treated according to a post-coloring procedure.

Example 8

The hairdresser studies the condition of hair to be colored, determinesa required number of layers of hair and draws up a coloring scheme toobtain a desired result on the hair. This case concerns primary coloringfor hair of the same length, like in a bob haircut.

The hairdresser selects the scheme for separating the hair into thehorseshoe-shaped sections according to the anatomical points of the head(see FIGS. 11A-11E). The hair separation into the horseshoe-shapedsection is performed as described above.

Subsections of hair are isolated in each section, and each subsection ofhair is fixed with a clamp. The activity of the hair growth phasesallows the hairdresser to select two layers with two grabbing levels.

The hairdresser grabs each subsection of hair and pulls it away in thedirection of the cut line of the hair. Layers of shorter hair above thegrabbing level are blown out of the subsection of hair with a blowdryer.

The hairdresser then proceeds to the hair coloring process.

In each subsection of hair, it is supposed to color the hair with adarker tone at their roots and make a transition to a light tone (blond)at the ends of the subsection of hair. A coloring scheme like the oneshown in FIG. 7 may be used in this case, but with three triangles(corresponding to three layers of long, medium-length and short hair)and other tone numbers. More specifically, in a base triangle (denotingthe layer of long hair), color 6N (medium blond) is indicated in theregion closest to the hair roots, color 8N (blonde) is indicated in themiddle region, and color 10N (platinum blonde) is indicated at the endsof the subsection of hair. In a smaller triangle (denoting the layer ofmedium-length hair), color 6N (medium brown) is indicated in the regionclosest to the hair roots, while color 7N+8N (light brown+blonde) isindicated at the ends corresponding to the middle region of the basetriangle. In the smallest triangle (denoting the layer of short hair),color 6N (medium brown) is indicated in the region closest to the hairroots, while color 7N (light brown) is indicated at the endscorresponding to the middle region of the base triangle.

The coloring formulas are applied to the obtained layers of hair inaccordance with the coloring scheme, whereafter each colored layer ofhair is wrapped in foil. All required layers of hair of each subsectionof hair in each section are treated in this manner.

The subsections of hair are colored, retreating a few centimeters fromthe hair roots each time.

To ensure a smooth transition from one color to another between thesubsections of hair, the color formulas may be applied to them in theform of a horizontal pattern.

The hairdresser waits enough time for the hair to be colored.

The color formulas are rinsed off the hair.

The colored subsections of hair are tinted to neutralize unwantedshades.

The hair is treated according to a post-coloring procedure.
